If IORESOURCE_MEM "lpass-rxtx-cdc-dma-lpm" or "lpass-va-cdc-dma-lpm"
resources is not provided in Device Tree due to any error,
platform_get_resource_byname() will return NULL which is later
dereferenced. According to sound/qcom,lpass-cpu.yaml, these resources
are provided, but DT can be broken due to any error. In such cases driver
must be able to protect itself, since the DT is external data for the
driver.
Adjust this issues by adding NULL return check.

Qualcomm LPASS macro codec driver parses registers in order to
detect version of the codec. It recognizes codecs v2.0 - v2.8, however
we know that there are earlier versions and 'enum lpass_codec_version'
has also v1.0, v1.1 and v1.2. If by any chance we run on unrecognized
version, driver will use random value from the stack as the codec
version.
Fix it by mapping such cases to an enum of value 0:
LPASS_CODEC_VERSION_UNKNOWN.

The driver for Qualcomm LPASS WSA macro codec was developed and tested
on codec v2.1, however v2.5 has significant changes in the registers.
The driver correctly works for v2.1 codec, but has issues when running
on SoC with v2.5 codec (so starting with SM8450, even though playback
works properly on that SoC).
Prepare the driver for handling differences in register layouts of newer
version. This does not have functional impact on older codec versions,
but just:
1. Renames few soc_enums and widgets as v2.1,
2. For registers being different in v2.5, moves the defaults and regmap
configuration to new structures,
3. Adds new 'struct wsa_reg_layout' with offsets and masks for few
registers, so most of the code can stay unchaged on v2.5,
4. Chooses proper widgets, regmap config and register layout based on
version of the codec.

We propose four patches to solve headphone detection and suspend issues.
And there are several registers that should be read-only registers. So
we create es8326_writeable_register, and set these registers to false.
It is incorrect to request the input pin format of the destination widget
using the output pin index of the source module as the indexes are not
necessarily matching.
moduleA.out_pin1 can be connected to moduleB.in_pin0 for example.
Use the dst_queue_id to request the input format of the destination module.
This bug remained unnoticed likely because in nocodec topologies we don't
have process modules after a module copier, thus the pin/queue index is
ignored.
For the process module case, the code was likely have been tested in a
controlled way where all the pin/queue/format properties were present to
work.
Update the debug prints to have better information.

There are two hardware connection methods for DMICs on the MT6358. In cases
where more than two DMICs are used, we need to time-multiplex these DMICs.
Therefore, we need to dynamically switch the modes of these DMICs based on
the actual usage scenarios.
---- DMIC1
AU_VIN0 ---
---- DMIC2
AU_VIN2 --- ----DMIC3
When we want to use DMIC1/2, configure it to one-wire mode. When we want to
use DMIC1/3, configure it to two-wire mode.

In some cases, depending on system design, the MICBIAS pins on the
chip are not needed as such, but a couple of extra GPIO pins would be
useful. This patch allows the MICBIAS pins to be configured in the
device tree as general purpose output pins, controlled via the GPIO
framework.
Owing to their originally intended purpose there are some limitations:
when the MICBIAS pins are deactivated, they will float, so will likely
need a pulldown in many applications. When activated, they will
assume the voltage specified by the micbias1-vg and micbias2-vg
properties, respectively, meaning that the resulting output voltage
will be 2.0 V, 2.5 V or AVDD .

This patchset provides ASoC support for the latest family
of Cirrus Logic multichannel, high performance audio ADCs.
The devices that are supported are CS5302 (2 channel ADC),
CS5304 (4 channel ADC), and CS5308 (8 channel ADC).
The value “-ENOMEM” was assigned to the local variable “ret”
in one if branch after a devm_kzalloc() call failed at the beginning.
This error code will trigger then a pcmdevice_remove() call with a passed
null pointer so that an undesirable dereference will be performed.
Thus return the appropriate error code directly.

priv->pdev pointer was set after being used in
fsl_asoc_card_audmux_init().
Move this assignment at the start of the probe function, so
sub-functions can correctly use pdev through priv.
fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the
dev struct, used with dev_err macros.
As priv is zero-initialised, there would be a NULL pointer dereference.
Note that if priv->dev is dereferenced before assignment but never used,
for example if there is no error to be printed, the driver won't crash
probably due to compiler optimisations.
